Had abscess tooth for two weeks won't go away is this dangerous and what do i need to do?

RCT or debridement: If it is an endo abscess (nerve hurts), root canal must be performed on the tooth. If it is a periodontal abscess, good scaling and root planing (debridement) should be done. Eliminate the cause of abscess (poor occlusion, eliminate area of food impaction). Even though it usually isnot dangerous, abscess could be painful and should be treated asap to avoid damage to surrounding bone.

SEE A DENTIST: An abscessed tooth likely won't go away on its own. An abscess is an infection! so, yes, it is dangerous if left untreated--it can kill you. Therefore, go see a dentist and get it treated asap!

Potentially : An abscess is bacteria, dead necrotic tissue and leaking foul smelling puss. Please get treatment. Depending on the severity and location your dentist may prescribe a round of antibiotics prior to treatment.

Dangerous, see a DDS: Infections don't resolve or go away on their own. The cause of the infection has to be determined and then it requires appropriate treatment. Not all teeth can be saved. The longer the infection remains, the more destruction to surrounding tissues, the greater the chance of spread and serious complications to other parts of your body and the harder it is to treat. See a dentist asap.

Needs treatment: An abscessed tooth will cause you to seek treatment immediately due to the pain, unless the abscess has caused a route for drainage (reducing pressure=less pain). It will not resolve on its own: it may have several means of occurring, dental or periodontal and will likely need a root canal treatment. It can be very dangerous especially in the lower jaw (swelling can cause asphyxiation).
